5.7.7 Inputs
The access manager has 4 inputs IN1 to IN4.
Function of the inputs
The inputs are used for the inquiry of sensors such as door-opener key, door handle
contact, door frame contact, bolt contact, vandal contact, pass-through contact (e.g.,
turnstile, light barrier), etc.
The function of the individual outputs depends on the settings of the terminal soft-
ware.
Principle
The inputs (IN1-IN4) are connected to GND using a simple switch or relay contact. An
open input is recognized as “high” due to the internal pull-up resistor. Ground poten-
tial equals “low.”
5.7.7.1 Line monitoring
The inputs can be designed as follows:
• Without line monitoring
• With line monitoring (if supported and activated by the terminal software)
Line monitoring allows the terminal software to detect the states short circuit and in-
terruption, in addition to the states active (input closed) and not active (input open)
and report them to the higher-level system.
The current states of the inputs are signaled by light emitting diodes [}5.7.7.5].
